Macro Make Circle 3 Points/de

Beschreibung

Dieses Makro erstellt einen Kreis, der an 3 ausgewählten Punkten orthogonal oder in 3D im Optionsraum umschrieben wird. Punkte können Objekte wie Würfel, Zylinder usw. sein. Die ausgewählten Koordinaten bilden dann den Mittelpunkt dieser Formen.

Kreis, der auf drei ausgewählten Punkten aufgebaut ist

Anwendung

Drei Punkte oder Formen in der 3D-Ansicht auswählen und das Makro ausführen.
Wenn die Form eine Linie ist, wird die Koordinate der Mittelpunkt der Linie sein.

Optionen

Modus

Defaut:

Modus erstellt standardmäßig einen Kreis auf den drei Punkten oder Formen im 3D-Raum.

Die Reihenfolge der Auswahl der Angstformen beeinflusst den Winkel AXIS und kehrt die Neigung des Kreises um. In diesem Fall können Sie die Reihenfolge der Auswahl der Formen umkehren oder ändern.

Koordinaten X, Y, Z Wert 0 oder Ausrichtung erlaubt keine Berechnung, kann eine Division durch Null-Fehler zurückgeben und mit übersetzt werden. Die drei Punkte sind ausgerichtet.

Vue Face:

Erzeugt den Kreis in den Vorderansichten des ausgewählten Formulars 1, 2 oder 3

'Vue Dessus:'

Erzeugt den Kreis oben in der Formularansicht 1, 2 oder 3

Vue Droite:

Erzeugt den Kreis in der Ansicht von rechts in der gewählten Form 1, 2 oder 3

Ausrichtung auf

Form 1, 2, 3

Formen in der Reihenfolge ihrer Auswahl.

Zentrum anzeigen

Wenn dieses Kontrollkästchen aktiviert ist, wird ein Punkt in der Mitte des erstellten Kreises erstellt

Farben kombinieren

Wenn dieses Kontrollkästchen aktiviert ist, nimmt der Kreis die Farbe der entsprechenden Ansicht an.

View-Top (X, Y) = Blau (Axt Z)

Ansichtsfront (Z, X) = Grün (Axt Y)

Ansicht-Links (Z, Y) = Rot (Axt X)

Skript

Die drei Symbole müssen sich im selben Verzeichnis wie das Modul befinden.

Danksagung

The genesis of the macro Draft_Circle_3_Points sur le forum (PYTHON) coordonnées d'un point helped flachyjoe thanks.
The formula comes from cercle_3pts.pdf and used with the kind permission of its author.
The formula adapted by " galou_breizh " circle in 3D space comes from Circumscribed_circle
